A spokesman for the New York City Department of Environmental Protection told The Wall Street Journal that New York tap water is already renowned for its quality.

"Public health experts agree that New York City tap water is among the safest, highest quality in the world, a standard we confirm through more than 500,000 tests each year," he said.

But Molecule founder Adam Ruhf dismissed that claim.

"I don't want chemicals in my water. I don't even want chlorine in my water. Chlorine is like bleach. Do you want to drink bleach? No one wants to drink bleach. So that's my opinion on New York tap water,” Ruhf told the Journal.

In addition to being cleaner, Ruhf claimed his water tastes better. He said the taste difference is “subtle, but if you have a sensitive palate you can totally tell.”

He called his water "fluffy" and said it finishes smoothly. Shots of vitamins, mixtures of herbs and roots and even pH infusions can be added to orders of the artisanal water.

"It's about treating water a little more consciously, mindfully and respectfully," the 32-year-old owner added. "We are trying to change the way people think about water."

But some critics weren’t buying it.

“Calling all suckers. We’re not sure what's more unsettling: the fact that an East Village business is selling tap water for $2.50 a bottle, or that countless idiots will probably buy it,” James King wrote in the Village Voice.

"Molecule bottled water is ‘pure’ nonsense,” Steve Cuozzo of the New York Post wrote.
